I've had my bumper for a couple years now, and it was starting to show some surface rust, and I wanted to fix that. So I went and bought a quart of herculiner, and I sanded the bumper down to bare metal, primered it and lined it. it looks brand new and VERY pretty, I think. If it holds up as well as the interior of my jeep has, I'll be happy. As soon as I get my hands on a digicam, I'll put some pics on here for you guys.
